I located Leo on the 1920 census, living with his siblings Robert, Mary, and Frank at the family home at 1451 Avondale. What is particularly interesting about this census is that there is also a family listed at the same address of Sophia and Steve Szymanowski. Where there two Sophia Szymanowskis? Did Sophia Plenzler marry a Szymanowski? Frank married Sophia Szymanowski. Did Sophia Szymanowski have a sibling named Steve? More investigation in the near future! (I do believe this is the case, but have not plowed through the census records yet.)

Mrs. Harriet S. Plenzler, 79, of Rosemar Drive, died Sunday in her home. She was the widow of Leo Plenzler. Surviving are her sons, Leon and Philip, and sisters, Mrs. Marie Cichy, Mrs. Martha Klatt, and Agnes Konczal, and brother, William Lamarr. Services will be at 10 a.m. Wednesday in St. Stanislaus Church. The Rosary will be recited at 7 p.m. Tuesday in the Sujkowski Mortuary, where the body will be after 6:30 tonight.
